Zip tie mounts?

I've seen a few people on TW that have used those square zip tie mounts to clean up wiring. I've been trying to find these. I've checked Target and Staples and neither has them. Could someone tell me where to find them so I don't have to keep driving around town to find them?

 

Home depot has them in the electrical section.

 

Thanks.

 

Used these before with good sucess for high heat under hood stuff..

Not the place where I have bought them, just the pics for reference.

The 8" Velcro One-Wrap reusable straps are a great alternative to Zip ties. Makes it nice if you need to add a wire or remove one from the bundle. Wally world had a roll of 50 for not much. Most fabric stores stock them as well.

Ace Hardware here had the zip tie mounting squares. ultra clean surface before you stick the sticky back stuff, or they wont hold.
